If you want to tactfully avoid mentioning obese people in your ads, you can consider using more neutral or positive wording. Here are some suggestions: 1. **Focus on a healthy lifestyle**: Emphasize health and vitality, such as "People who seek health and vitality are welcome to participate." 2. **Positive body shape**: Use the expression "suitable for all body types", such as "suitable for people pursuing an ideal body shape." 3. **Emphasis on goal orientation**: Such as "People who seek to change and improve themselves" or "People who hope to achieve personal goals." 4. **Use vague descriptions**: For example, "People who look forward to shaping an ideal body shape." 5. **Focus on needs**: For example, "Friends who are interested in improving their body shape." 6. **Positive guidance**: Use the method of "Friends who pursue a healthy weight are welcome to join." The above wording can better convey the message while avoiding offending specific groups.
